摘要

为研究轻型竹结构房屋的抗震性能，通过对足尺2.44×3.66×2.6m的竹结构模型的振动台实验和推覆实验，讨论竹结构模型房屋的动力特性，确定竹结构房屋在地震作用下的破坏机理，研究了结构动力特性及地震反应的变化规律。试验结果表明：在0.3g以下的地震中，模型处于弹性状态；即使经过多次重复地震，模型结构仍然不会发生倒塌，而且破坏也很轻微。模型结构在0.1g、0.3g、0.4g和0.5g的地震中，模型结构的最大层间位移角小于规范中的限值。试验研究表明，轻型竹结构房屋能够满足我国建筑抗震设计规范中的8度抗震设防要求。

Abstract

To study seismic behavior of lightweight bamboo frame residential house, shake table tests were conducted using a full-scale model, which simulated a first floor room unit of a typical two storey house, 2.44m by 3.66m in plan and 2.6m in height. Earthquake lateral resistance was provided by glubam shear walls around the perimeter of the model. The test results indicate that the model performed elastically and had essentially no visual damage for 0.3g PGA. The tested glubam house can withstand applications of three different seismic ground motions in the order of 0.5g PGA without collapse. The observed damage remained noncritical for 0.5g PGA. Inter-story drift in the first story was generally below most code required values. After subjecting shakings of 0.5g PGA, the model was retested under a pushover loading condition and showed sufficient deformability. The tests reveal that glubam house can meet the requirements for the seismic intensity of 8 as described in the China Seismic Design Code.
